Measurement of Apparent Thermal Conductivity of Insulation Materials at Cryogenic Temperatures
Open accessAbstract
Efficient storage of cryogenic liquids such as liquid oxygen and liquefied natural gas depends on the development of reliable and high-performance insulation materials. However, thermal conductivity data for many potential candidates, including cellular glass, polyisocyanurate, and aerogel, remain limited under cryogenic and atmospheric pressure conditions. In this study, a dedicated experimental apparatus was designed and constructed to measure the apparent thermal conductivity of representative insulation materials. Tests were carried out on cellular glass slabs, high-density polyisocyanurate, aerogel blankets, and nitrile rubber curved panels at liquid-nitrogen temperatures and above. The results indicate that aerogel blankets exhibit the best insulation performance, with an apparent thermal conductivity as low as 0.0063 W/(m·K) at 110 K, significantly outperforming the other tested materials. These results offer valuable references for the selection, optimization, and practical application of insulation materials in cryogenic storage tanks.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
